Below are the latest papers in Atom-Ph, offering fresh insights into the structure and behavior of the atomic scale.
This paper proposes using linear Paul traps with single or multi-ion configurations to detect megahertz gravitational waves via graviton-photon conversion or relative-motion excitations, demonstrating that entangling vibrational qubits enhances signal probability by a factor of to surpass the standard quantum limit.
This paper presents a detailed computer simulation method to investigate the non-monotonic evolution of K-shell ionization and characteristic x-ray radiation angular distributions from high-energy electrons and positrons traversing oriented silicon crystals across a wide energy range (1–1000 GeV), with a specific focus on the underlying physical mechanisms such as dechanneling.
This study experimentally demonstrates that dysprosium atoms can be prepared in a long-lived metastable state with a large induced electric dipole moment of over 1 Debye and a reduced transition dipole moment of 7.65 Debye, enabling efficient single-photon excitation from the ground state through a three-state Stark interaction.
This paper presents a framework for quantifying spin-orbital entanglement in Cr-doped glasses by reconstructing electronic spinors from optical data, revealing a robust linear correlation between the von Neumann entropy and the ratio of spin-orbit coupling to crystal field strength.
Using a quantum simulator of 114 Rydberg atoms arranged in a kagome array, researchers successfully adiabatically prepared and characterized a disordered, correlated liquid state that exhibits strong agreement with theoretical predictions for a gapless U(1) Dirac spin liquid.
This paper presents a comprehensive investigation of He I line profiles for DB white dwarf spectroscopic analysis, utilizing SDSS DR17 data to compare traditional semi-analytical Stark profiles with new computer-simulated profiles while examining various physical effects such as frequency sampling, Doppler broadening, and 3D hydrodynamical corrections.
